Explore the forefront of offshore geotechnics for floating wind at the 1st International Seminar on Offshore Anchorage Systems (OASIS), hosted by the Université Gustave Eiffel in Paris, France, on September 24, 2026.
Join industry leaders, researchers, and experts for a unique event building on the momentum of ISFOG 2025 in Nantes. Held under the auspices of the ISSMGE, with the support of the French Society for Soil Mechanics (CFMS) and the Norwegian Geotechnical Society (NGF), OASIS 2026 is jointly organized by Université Gustave Eiffel (UGE) and the Norwegian Geotechnical Institute (NGI).
OASIS 2026 will showcase cutting-edge developments in floating offshore wind geotechnics, with a strong focus on next-generation anchoring systems. The program will feature four plenary sessions combining keynote presentations and panel discussions, addressing key challenges faced by developers, industry stakeholders, and research institutions.

WELCOME AND HOUSEKEEPING | Ana Page (NGI) & Christelle Abadie (UGE)
ON THE IMPORTANCE OF GEOTECHNICS IN FLOATING WIND PROJECTS | Phil Watson (University of Western Australia)
10h00 - 11h30 : Session I - Site investigation
Gain practical insights into offshore site investigation through real world experience, featuring experts from industry and certification.
Chaired by:
- Anders Hust Augustesen (GEO)
Engineering Director with 25 years of experience in consultancy, offshore wind development and academia. Experience with planning, scoping, supervision and interpretation of geotechnical investigations for national and international offshore structures like wind turbines, oil and gas platforms, major bridges, piers as well as onshore structures. Comprehensive experience in design of different types of foundations like piles, suction buckets, anchor blocks etc. Actively involved in teaching and researching on university level. Authored and co-authored numerous scientific papers, reports and text books. Engaged in international technical communities and standardisation bodies. - Oda Mohus (NGI)
10:00 – 10:25 | ADAPTING SITE INVESTIGATION APPROACHES FROM FIXED TO FLOATING OFFSHORE WIND
How do site investigation requirements differ between bottom-fixed and floating offshore wind, and which established methods can be transferred directly versus adapted or newly developed for floating wind? How is the GIFT project helping to close gaps in ground investigation guidance for floating wind? Will there be a need for new standards? Will there be a need for new test types and increased accuracy for some soil parameters?
Dive into these challenges with experts:
10:25 – 10:40 | NEW GROUND AND METOCEAN CONDITIONS
What new ground conditions, seabed environments, water depths, and metocean conditions are likely to be encountered in floating wind developments, and how should site investigation strategies adapt to these settings?
Dive into these challenges with expert:
10:40 – 11:30 | GROUND MODEL-BASED DESIGN AND UNCERTAINTY
How can a ground-model-based approach improve the planning / execution of site investigations and design for floating offshore wind? How to efficiently manage uncertainties in floating wind developments (investigation strategies and ground model uncertainty translating into design)? Will there be need to measure some soil parameters more accurate?
